Typing on the Wii is actually kinda easy. There's this cool feature it has where whenever you type something, it gives you a list of words for you to select and it would show it there. It's hard to explain but it's actually kinda fun typing with the remote. I'm also kinda a fast typer so it's no problem for me.
I see. This small paragraph that you type with the wii, would probably take you thirty minutes or so on the psp (that is a bit of an exageration, but it would take you awhile) because the psp doesn't have any neat features with words, and the letters you type are done like this:
In order to reach the caps 'A' you would have to press the 'X' button four times, and then press the 'R' button to confirm that is the one you want, then do that with the rest of the letters, see a pain *sigh*.
